Tutorial: obj.is

Require javascript-object-paraphernalia

var obj = require('javascript-object-paraphernalia')

Declare some variables to work with in the following examples

function TestClass() {}
var object = {},
    testClass = new TestClass(),
    func = function() { return false },
    str = "I'm a string"

Use obj.is to test an assertion about an object's type

  obj.is(object, 'Object')        // === true
  obj.is(object, 'object')        // === true
  obj.is(func, 'Function')        // === true
  obj.is(func, 'function')        // === true
  obj.is(str, 'String')           // === true
  obj.is(str, 'string')           // === true

  // testClass returns true to either its Class or Object
  obj.is(testClass, 'TestClass')  // === true
  obj.is(testClass, 'Object')     // === true

  // testing for a class name is not case insensitive  
  obj.is(testClass, 'testclass')  // === false
